Steel A285 Annealed vs A285 Normalized
Steel · A285 temper comparison
A285 Annealed and A285 Normalized are two conditions of the same steel grade, A285: Annealed versus Normalized. The chemistry is identical, so every difference below comes from the condition. A285 Normalized is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 225 MPa (32.6 ksi) for A285 Annealed, about 16% more; tensile strength follows at 455 MPa (66 ksi) vs 415 MPa (60.2 ksi). A285 Normalized is harder — 132 HB against 118 HB for A285 Annealed — which matters for wear surfaces and threads.
A285 NormalizedChoose it when strength drives the design, or when surface hardness matters.
A285 Annealed vs A285 Normalized: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

A285 Annealed vs A285 Normalized — frequently asked
Is A285 Normalized stronger than A285 Annealed?
Yes. A285 Normalized has a typical yield strength of 260 MPa (37.7 ksi) against 225 MPa (32.6 ksi) for A285 Annealed — about 16% more. Tensile strength is 455 MPa (66 ksi) vs 415 MPa (60.2 ksi).
Which condition does FabDigit quote by default, Annealed or Normalized?
HR is the default A285 condition in the FabDigit quote flow (neither Annealed nor Normalized). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose A285 Annealed over A285 Normalized?
Pick A285 Normalized when strength drives the design, or when surface hardness matters.
